A UNIQUE, UNUSUAL and SHOWY pseudomorph of quartz after quartz and very nicely accented with lustrous, iridescent, black brookite crystals. This fine, old-timer hails from the famous Magnet Cove District of Arkansas. The specimen is dominated by a large, euhedral quartz pseudo. You can see the cavity in the termination where a brookite crystal was dissolved out. The scattering of sharp brookites highlight this uncommon and excellent piece from a CLASSIC locality. Ex. George Feist Collection.
